To all whom 'it may concer/n.:

Be it known that I, VILLIAM C. MITCH- ELL, a citizen of the United St-ates, residing at Sydney, Province of Nova Scotia, and Dominion of Canada, have invented a new and useful Tilting-Pan Coke-Discharging Apparatus, of which the following is a specification.

The invention relates to an apparatus for handling coke and similar loose material and for transferring the same from ovens and like receptacles to railroad cars, canal boats, barges, and similar means of transportation, and for loading it into the same.

The object of the present invention is to simplify and improve the construction of machines for handling coke and similar loose material, and to increase the eiiiciency of the same and to enable such machines to project outwardly to carry the material out over the car or vessel to be loaded, and at the completion of each dumping operation to move inwardly out of the way of such cars, boats or vessels into which t-he machine is loading.

Another object of the invention is to provide a coke handling apparatus, adapted to coperate with a whole line of ovens, and capable of being rapidly transferred from 0 one oven to another and being controlled both as to such movements and also in its coke handling operations from a single source of power.

With these and other objects in view, the

5 invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended: it beingunderstood that various` changes in the fo-rm, proportio-n, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the in- Like numerals of reference designate corresponding parts in all the figures of the drawings. Y

In the embodiment of the invention illustrated in the accompanying drawings, the coke handling apparatus comprises in its construction a wheeled frame 1, designed to be constructed of any suitable material and provided at its bottom portion with spaced platforms 2, located at opposite sides of a tiltable coke receiving platform or pan 3, arranged centrally of the wheeled frame and adapted when in a horizontal position to receive a charge of coke from an oven 4, and capable of having its inner or rear end elevated to arrange it in an inclined position, as illustrated in dotted lines in Fig. 1 of the drawings for discharging its contents into a car 5. The coke ovens 4 are provided with projecting ledges 6, and the charge of coke is transferred from the oven to the tiltable plat-form 3 by any suitable means. The frame 1 is provided at opposite sides of the tiltable platform with grooved supporting Wheels 7 arranged to run on tracks 8 and adapted to enable the coke handling apparatus to be moved laterally to transfer it from one coke oven to another, in order to handle the coke of an entire series of ovens. The wheels 7 at one side of the frame are connected by a longitudinal shaft or aXle 9, and mo-ti-on is communicated to the same for propelling the apparatus by means of spur gearing 10, which connects the longitudinal shaft or axle with a motor actuated driving shaft 11, a clutch 12 of any suitable construction being employed for throwing the propelling gearing into and out of operation.

The tilting pan or platform, which is constructed of metal, or other suitable material, is composed of a horizontal bottom and sides, having downwardly and inwardly inclined lower portions and vertical upper portions. The tiltable pan is provided at its front end with laterally extending pivots 13, preferably in the form of studs and having Shanks 14, provided with integral attaching plates 15, arranged at an inclination and bolted or otherwise secured to the sides of the tiltable pan, as clearly illustrated in Fig. 4 of the drawings, but the laterally extending front pivots 13 may be mounted on the pan in any other desired manner. The pivots 13 are arranged in openings or bearings 16 at the outer o-r front ends of slidable supporting bars or members 17, extending longitudinally of the pan at opposite sides thereof and adapted to support the pivoted end of the tiltable pan in an extended position over the car or vessel into which the coke or other material is being loaded. The slidable supporting bars or members are provided with forked or bifurcated inner end portions 18, curved downwardly and straddling longitudinal beams 19 of the frame of the apparatus. Anti-friction wheels 2O are mounted in the forked or bifurcated inner portions of the supporting bars or members and are arranged to run along the lower face of the beams 19, which are preferably I beams, but any other form of track may be employed. The anti-friction wheels 20 are mounted on suitable pivots or axles 21, which pierce the sides of the bifurcated or forked portions of the supporting bars or members and suitably secured to the same.

The slidable supporting bars or members are equipped at points intermediate of their ends with anti-friction wheels 22, arranged in pairs and located at opposite sides of the supporting bars or members and mounted on suitable shafts or pivots 23. The shafts or pivots 23 pass through bearing openings 24 of the supporting bars or members,`

sleeves 25 or other suitable anti-friction devices being preferably arranged on the shafts or pivots 23. The intermediate wheels 22 operate in inclined longitudinally disposed guiding slots 26 of guides 27, which are mounted on the frame of the apparatus at opposite sides of the tiltable pan. Each of t-he guides 27 preferably consists of a pair of spaced parallel side plates 28, suitably connected atthe top and bottom and reinforced by marginal flanges and by means of flanges 29,- which extend around t-he inclined guiding slots 26. The weight of the tiltable pan and its contents maintains the inner anti-friction wheels in engagement.

with the track beams 19 and holds the intermediate wheels against the bottom of the inclined guides, formed by the slotted side plates. The tiltable pan when raised to dump its contents is ymoved outward simultaneously with the tilting movement to arrange it over the car or vessel into which the coke or other material is to be dumped, and it is automatically moved inward and returned to its initial posit-ion after each dumping operation has been completed, in order to arrange it out of the way of a locomotive` box cars, or other medium of transportation.

vThe tiltable pan is also equipped at its inner or rear end with laterally project-ing studs or pivots 30, upon which are mounted flanged anti-friction wheels 31 and pulleys or sheaves 32. The studs or pivots 3() are provided with attaching plates orportions 33, which are secured to the pan at opposite sides thereof. The wheels 31 are arranged to engage and run on inclined guides 34, rigidly mounted on the frame of the apparatus at opposite sides of the inner or rear end of the tiltable pan and extending upwardly and forwardly and preferably consisting of angle bars or members, secured to the inclined edges of triangular plates or supports 35, but any other form cf inclined or substantially inclined guide may be employed for permitting a gradual outward movement of the tiltable pan, when the latter is raised and for causing a positive inward movement of the pan and a return of the same to its initial position when the pan is lowered.

The pulley 32 receives loops 36 of hoisting ropes 37, extendingupwardly and forwardly from drums 38 and passing over overhead pulleys 39 and extended therefrom to and around the pulleys 32 and back to the top of the frame, forming the loops 36. The outer terminals 40 of the hoisting ropes are attached to projecting plates 41 of the frame at points adjacent to the overhead pulleys, as clearly shown in Fig. 1 of the drawings. The pull on the tiltable pan or platform through the upwardly and forwardly inclined loops of the hoisting ropes tends to elevate the inner or rear end of the platform and to urge the same outwardly. ln the drawings, the frame of the machine is provided with spaced upwardly extending sides 42, connected at the top by a transverse portion 43 to form a derrick and consisting of vertical supporting posts or port-ions 44 and inclined bracing portions 45,but any other suitable form of framework may be employed. The overhead pulleys 39 are mounted on a transverse shaft 46, journaled in suitable bearings 47 at the top of the frame. The drums 38, which are spaced 'apart to arrange the hoisting ropes at opposite sides of the pan, are mounted onV a transverse drum shaft 48, located beneath the frame and journaled in suitable bearings thereof, and connected at one end by beveled gears 49 and 50 with the motor actuated shaft 11, a suitable clutch 51 being employed for thro-wing the hoisting mechanism into and out of operation when desired. The shaft 11 is connected by spur gearing 52 with a tubular shaft- 53, arranged on the' longitudinal shaft or axle 9 and connected by spur gearing 54 with'the shaft of an electric motor 55. Any other arrangement of gearing, however, may begemployed for transmitting motion from-the electric motor to the shaft 11. By connecting the motor actuated shaft 1l with the gearing of the hoist-ing mechanism and with the gearingl of the propelling mechanism, the means for moving the, apparatus from one oven to another and for raising and lowering the tiltable platform are operated from a single source of power.

When it is desired to tilt the coke receiving platform or pan, the motor is started and the clutch 51 is operated to connect the drum shaft 48 with the motor actuated or driving shaft 11. This causes the drums to revolve and wind up the hoisting ropes, which raise the inner or rear end of the pan. At the same time as a result of the force exerted by the pull of the inclined portions of the ropes and the force exerted by gravity, the pan iscarried both forwardly and upwardly, and is slightly elevated at its front end through the inclined front guides. The forward longitudinal movement of the tiltable pan or platform, which occurs simultaneously with the raising of the inner or rear end, is controlled by the rear inclined guides, and when the pan reaches the limit of its forward longitudinal movement by reason of the intermediate anti-friction wheels 22 having reached the front terminals of the inclined front guides, the pan swings upward on its front pivots 13 and moves away from the rear guides until it is inclined suliiciently to discharge its contents into the car or vessel, as clearly illustrated in dotted lines in Fig. 1 of the drawings. The motor is then reversed to lower the inner or rear end of the tiltable pan or platform, and when the inner or rear antifriction wheels 31' engage the inner or rear inclined guides, they cause a positive inward sliding movement of the pan or platform and return the same to its initial position, where it is out of the way of the locomotive, boX cars, vessels and the like. The weight of the inner or rear end of the platform is sufficient to cause the wheels 31 to roll down the rear inclined guides and draw the pan or platform inwardly. By throwing into action the other clutch 12, a lateral motion is imparted to the apparatus, which may thereby be moved along t-he track and arranged at any desired point, so that the apparatus may be employed for unloading and handling the coke of an entire series of ovens, and may be transferred successively from one oven to another.

While I have illustrated in the drawings hoisting mechanism having spaced hoisting ropes connected with the tiltable pan or platform, yet it will be clear that other forms of hoisting mechanism may be employed. When necessary the coke is quenched and cooled while within the apparatus, and any suitable means may be employed for this purpose.
